A Note on Invariant Measure on the Local Gauge Group
Wei-Min Sun, Xiang-Song Chen, Fan Wang
In this paper we investigated the problem of the existence of invariant meaures on the local gauge group. We prove that it is impossible to define a {\it finite} translationally in…
A simple proof that does not have a Haar measure
Wei-Min Sun, Xiang-Song Chen, Fan Wang
We give a simple proof that there does not exist a Haar measure on the group .
A Note on Functional Integral over the Local Gauge Group
Wei-Min Sun, Xiang-Song Chen, Fan Wang
We evaluated some particular type of functional integral over the local gauge group C^{\infty}({\bf R}^n, U(1)) by going to a discretized lattice. The results explicitly violates t…
Some Problems in Defining Functional Integration over the Gauge Group
Wei-Min Sun, Xiang-Song Chen, Fan Wang
We find that sometimes the usual definition of functional integration over the gauge group through limiting process may have internal difficulties.
Quantization of gauge theory for gauge dependent operators
Xiang-Song Chen, Wei-Min Sun, Fan Wang +1
Based on a canonically derived path integral formalism, we demonstrate that the perturbative calculation of the matrix element for gauge dependent operators has crucial difference…
How does baryon magnetic moment relate to its spin structure
Xiang-Song Chen, Di Qing, Fan Wang
A model independent, field theoretical relation between baryon magnetic moment and its spin structure is derived and it is explained why constituent quark model is a good approxima…
